Abstract:	The present technique used in the establishment of minimum-energy, circular, geocentric orbits of artificial satellites requires the addition of two velocity increments to the satellite. The initial velocity increment is imparted in the "booster" state to place teh satellite in a transfer ellipse. This ellipse is tangent to teh earth's surface, and also to teh desired circular orbit. The second velocity increment is added when the desired orbital altitude is reached. Since this occurs at the apogee of the transfer ellipse orbit, it is added linearly to the satellite's velocity vector at this time.
